Using radar interferometry, a technique used to target displacements to the nearest centimetre, Effigis’ Earth Observation Team tried to determine whether the impact of the earthquake could be measured.
On May 23, 2015, the highest volcano in the Galapagos Islands, Wolf Volcano, erupted for the first time in 33 years. Using satellite imagery and radar interferometry, our team tried to determine whether the soil had moved specifically due to this eruption.
There are many risks inherent to each steps of a mine lifecycle, and they are all quite different from one another. How can we better manage and especially evaluate these risks?
It’s true that it does not easily spring to mind that the images captured by Earth observation satellites, nowadays with submetric spatial resolution at best, can produce displacement measurements with a precision measured in centimetres or millimetres, as the experts claim. But what exactly does this involve?
On Saturday, May 1, 2015, Tunisians raised a huge flag equivalent to 19 football fields to beat the Guinness World Record for the largest flag in the world.
